Description

Technical Field

[0001] This invention relates to the field of pollution prevention and control of clam fouling in water conveyance systems, and in particular to a solenoid structure for a magnetic heat clam cleaner for water conveyance pipelines. Background Technology

[0002] The mussel *Rhododendron molle* (commonly known as freshwater mussel) has extensively invaded major water conveyance systems and hydropower projects in recent years, causing serious biofouling problems. It is particularly prone to causing blockages in cooling water supply systems, even leading to unplanned project shutdowns. *Rhododendron molle* larvae attach to the inner walls of water pipes, gradually developing and secreting byssal threads to stably adhere to the surface. As the *Rhododendron molle* aggregates, it causes pipe corrosion and blockage, reducing water conveyance efficiency and seriously threatening the safety and lifespan of engineering facilities. This mussel biofouling problem is widespread both domestically and internationally, posing a threat not only to engineering safety but also potentially causing adverse impacts on ecosystems.

[0003] Currently, the main solutions to the biofouling problem of swarm clams include physical removal, chemical treatment, and biological control. While these methods can mitigate the harm caused by swarm clams to some extent, they all have drawbacks such as high implementation difficulty, high cost, and potential environmental pollution. For example, physical removal requires specialized equipment and a large workforce, and suffers from high equipment wear and tear and maintenance costs; chemical treatment, while effective to some extent, carries the risk of residual chemicals polluting water; and biological control is unstable, time-consuming, and difficult to completely eliminate swarm clams. Therefore, there is an urgent need for a more efficient, environmentally friendly, ecological, safe, and economical method for controlling swarm clams in engineering water pipelines.

[0004] Magnetothermal technology, an innovative clam-removal technique, generates a high-frequency, strong magnetic field by arranging a solenoid structure inside the water supply pipeline. This activates superparamagnetic nanoparticles (SMNPs) suspended in the water. Under the influence of the magnetic field, the nanoparticles rapidly heat up, generating a localized thermal effect that effectively kills clam larvae in the water. It also drives away or directly kills larvae already attached to the pipe walls. Magnetothermal technology avoids the mechanical damage caused by physical removal and prevents secondary pollution of the water, providing a more efficient and sustainable solution for biofouling treatment. However, traditional solenoid structures are long and immobile, requiring installation only in long, straight water supply pipelines. Most water supply pipelines have complex shapes, including bends, branches, and varying diameters. The traditional long solenoid structure installed at bends can cause blockages, affecting the normal operation of the clam remover within these complex pipelines, and also making installation, disassembly, and maintenance inconvenient. Summary of the Invention

[0005] This invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one objective of this invention is to provide a solenoid structure for a magnetic thermal clam remover for water pipelines, suitable for the complex shapes of water pipelines, easy to install, disassemble, and maintain, safe and reliable, and capable of efficiently removing clams from water pipelines while reducing manual intervention.

[0006] According to an embodiment of the present invention, a solenoid structure for a magnetic thermal cleaner for water pipelines is arranged inside a water pipeline, comprising solenoid modules connected in series. The solenoid modules are short solenoid modules, and adjacent solenoid modules are movably connected. The movable connection between adjacent solenoid modules is suitable for being arranged at bends or non-bends in the water pipeline. Each solenoid module is used to generate a strong alternating magnetic field.

[0007] From the perspective of installation, disassembly, and maintenance, since multiple solenoid modules are connected in series, each solenoid module is a short solenoid module. That is, the axial length of a single solenoid module is shorter than the axial length of a traditional long solenoid structure that cannot move relatively on its own. Multiple short solenoid modules connected in series replace the traditional long solenoid structure that cannot move relatively on its own and are arranged on the inner wall of the water supply pipeline. The movable connection parts between adjacent solenoid modules are correspondingly arranged at the bends and branches of the water supply pipeline. Multiple short solenoid modules and the movable connection between multiple short solenoid modules can rotate freely to adapt to various complex shapes of water supply pipelines. At the same time, for water supply pipelines with different diameters, the radial dimensions of the solenoid modules can be designed accordingly to match the inner diameter of the water supply pipeline. Therefore, the solenoid structure for the magnetic thermal cleaner of water pipelines in this embodiment of the invention has excellent flexibility and versatility, and can smoothly adapt to complex pipeline shapes such as bends and branch pipes without affecting the normal flow of water. It avoids the blockage problems and installation difficulties that may occur at bends in traditional long solenoid structures where the solenoid itself cannot move, ensuring the normal operation of the cleaner in various water pipeline environments. Of course, since multiple solenoid modules are connected in series, the solenoid structure for the magnetic thermal cleaner of water pipelines in this embodiment of the invention can still be easily installed in long, straight water pipelines without bends. Because the solenoid modules are modularly designed, they are easy to install, disassemble, and maintain. The modular design of the solenoid modules not only allows for quick replacement or repair according to actual needs, but also greatly reduces equipment maintenance costs and operational difficulty, making them suitable for long-term use in large-scale projects.

[0008] In terms of the effectiveness of removing and controlling clams, the solenoid module generates a strong alternating magnetic field in the water supply pipeline through an external power supply, activating the superparamagnetic nanoparticles suspended in the water. Under the action of the magnetic field, the nanoparticles heat up rapidly, generating a local thermal effect. This local thermal effect effectively kills clams larvae in the water supply pipeline and repels or kills adult clams attached to the pipeline wall. Thus, the solenoid structure of the magnetic thermal clam remover for water supply pipelines in this embodiment of the invention achieves efficient, environmentally friendly, and economical clam removal and killing effects, while avoiding the corrosion or pipeline damage problems that may be caused by traditional chemical cleaning.

[0009] The solenoid module adjusts the magnetic field frequency and intensity via an external power supply, enabling automated and intelligent control. The monitoring system adjusts the magnetic field frequency and intensity in real time, covering the long-wave to medium-wave range to ensure the magnetic nanoparticles generate sufficient heat in a short time. The magnetic field strength is required to penetrate deep into the inner wall of the water pipe to effectively cover the entire water flow channel, killing larvae or forcing them to detach from their attachment surface. This ensures optimal eradication results under various operating conditions, reducing manual intervention and enhancing the intelligence level of the clam-removing system.

[0010] In summary, the solenoid structure for the magnetic thermal cleaner for water pipelines according to the embodiments of the present invention has the following advantages:

[0011] (1) Adapting to complex water pipeline shapes: Through the design of movable series and short solenoid modules, it can smoothly pass through complex water pipelines, including small-radius bends, ensuring the wide applicability of the cleaner in various water transmission systems. Multiple short solenoid modules are combined in series to ensure that it can adapt to pipelines with small bending radii.

[0012] (2) Efficient magnetic field generation: The solenoid module 10 can customize the magnetic field parameters according to the shape and size of the water pipeline to ensure that the swamp clams attached to the pipeline can be killed efficiently and the cleaning cycle of the water pipeline can be extended.

[0013] (3) Modular design, easy to disassemble and maintain: The solenoid structure 1000 adopts a modular design, which is easy to disassemble and maintain, suitable for long-term online operation, and reduces the cost and difficulty of cleaning the pipeline.

[0014] (4) Automated and intelligent control: It can be combined with modern control technology to achieve automated regulation. The magnetic field strength and frequency are adjusted in real time through the monitoring system to ensure that the best sterilization effect is maintained under different working conditions, reduce manual intervention, and improve the intelligence level of the system.

[0015] (5) Safe and reliable: It can avoid the corrosion or pipeline damage problems that may be caused by traditional chemical cleaning.

[0016] In some embodiments, adjacent solenoid modules are connected by a movable connector, which is adapted to be arranged at bends or non-bends in the water supply pipeline.

[0017] In some embodiments, the movable connector is a telescopic universal joint.

[0018] In some embodiments, the solenoid module includes a solenoid body, a cylindrical frame, and a shock absorber. The solenoid body is fixed to the outer periphery of the cylindrical frame, and the shock absorber is fixed to the outer periphery of the cylindrical frame. The shock absorber is used to support the inner wall of the water supply pipe so that there is a gap between the solenoid and the inner wall of the water supply pipe.

[0019] In some embodiments, the plurality of solenoid modules may be the same or different in size.

[0020] In some embodiments, the number of turns, wire diameter, and length of the solenoid body are determined according to the diameter and length of the corresponding water supply pipe.

[0021] In some embodiments, the solenoid body includes a metal solenoid and an insulating layer covering the surface of the metal solenoid.

[0022] In some embodiments, the metal solenoid is a high-electricity metal solenoid.

[0023] In some embodiments, the telescopic universal joint is connected between the cylindrical frames of adjacent solenoid modules.

[0024] In some embodiments, the magnetic field frequency and intensity of the plurality of solenoid modules are controlled independently.

[0025] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0031] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0032] The following is combined Figures 1 to 2 The solenoid structure 1000 for a magnetic thermal cleaner for water pipelines according to an embodiment of the present invention is described.

[0033] like Figure 1 and Figure 2 As shown, the solenoid structure 1000 for the magnetic heat clam cleaner for water supply pipelines in this embodiment of the invention is arranged inside the water supply pipeline. Here, the water supply pipeline refers to the water supply pipeline in the water supply system and hydropower project that needs to be protected against clam fouling. Under normal circumstances, the shape of the water supply pipeline is complex, with bends, branch pipes, and different pipe diameters.

[0034] The solenoid structure 1000 for a magnetic thermal cleaner for water pipelines in this embodiment of the invention includes solenoid modules 10 connected in series. The solenoid modules 10 are short solenoid modules, and the solenoid modules 10 are connected by a movable connection. The movable connection between adjacent solenoid modules 10 is suitable for being arranged at bends and non-bends in the water pipeline. Each solenoid module 10 is used to generate a strong alternating magnetic field.

[0035] From the perspective of installation, disassembly, and maintenance, since multiple solenoid modules 10 are connected in series, each solenoid module 10 is a short solenoid module 10. That is, the axial length of a single solenoid module 10 is shorter than the axial length of a traditional long solenoid structure that cannot move relative to itself. Multiple short solenoid modules connected in series replace the traditional long solenoid structure that cannot move relative to itself and are arranged on the inner wall of the water supply pipeline. By utilizing the movable connection parts between adjacent solenoid modules 10, they are correspondingly arranged at the bends and branches of the water supply pipeline. The movable connection between multiple short solenoid modules 10 can freely rotate to adapt to various complex shapes of water supply pipelines. At the same time, for water supply pipelines with different diameters, the radial dimensions of the solenoid modules 10 can be designed accordingly to match the inner diameter of the water supply pipeline. Therefore, the solenoid structure 1000 for a magnetic thermal cleaner for water pipelines in this embodiment of the invention has excellent flexibility and versatility, and can smoothly adapt to complex pipeline shapes such as bends and branch pipes in water pipelines without affecting the normal flow of water. It avoids the blockage problems and installation inconveniences that may occur at bends in water pipelines with traditional, relatively immobile long solenoid structures, ensuring the normal operation of the cleaner in various water pipeline environments. Of course, since multiple solenoid modules 10 are connected in series, the solenoid structure 1000 for a magnetic thermal cleaner for water pipelines in this embodiment of the invention can still be easily installed in long, straight water pipelines without bends. Because the solenoid modules 10 are modularly designed, they are easy to install, disassemble, and maintain. The modular design of the solenoid modules 10 not only allows for quick replacement or repair according to actual needs, but also greatly reduces equipment maintenance costs and operational difficulty, making it suitable for long-term use in large-scale projects.

[0036] In terms of the effectiveness of removing and controlling clams, the solenoid module 10 generates a strong alternating magnetic field in the water pipeline through an external power supply, activating the superparamagnetic nanoparticles suspended in the water. Under the action of the magnetic field, the nanoparticles heat up rapidly, generating a local thermal effect. This local thermal effect effectively kills clams larvae in the water pipeline and removes or kills adult clams attached to the pipeline wall. Thus, the solenoid structure 1000 of the magnetic heat clam remover for water pipelines in this embodiment of the invention achieves efficient, environmentally friendly, and economical clam removal and killing effects, while avoiding the corrosion or pipeline damage problems that may be caused by traditional chemical cleaning.

[0037] The solenoid module 10 adjusts the magnetic field frequency and intensity via an external power supply, enabling automated and intelligent control. The monitoring system adjusts the magnetic field frequency and intensity in real time, with the frequency range from long-wave to medium-wave to ensure the magnetic nanoparticles generate sufficient heat in a short time. The magnetic field strength is required to penetrate deep into the inner wall of the water pipe to effectively cover the entire water flow channel, killing larvae or forcing them to detach from their attachment surface. This ensures optimal killing results under various operating conditions, reduces manual intervention, and enhances the intelligence level of the clam-removing system.

[0038] In summary, the solenoid structure 1000 for a magnetic thermal cleaner for water pipelines according to embodiments of the present invention has the following advantages:

[0039] (1) Adapting to complex water pipeline shapes: Through the design of movable series and short solenoid modules 10, it can smoothly pass through complex water pipelines, including small radius bends, ensuring the wide applicability of the cleaner in various water transmission systems. Multiple short solenoid modules 10 are combined in series to ensure that it can adapt to pipelines with small bending radii.

[0040] (2) Efficient magnetic field generation: The solenoid module 10 can customize the magnetic field parameters according to the shape and size of the water pipeline to ensure that the swamp clams attached to the pipeline can be killed efficiently and the cleaning cycle of the water pipeline can be extended.

[0041] (3) Modular design, easy to disassemble and maintain: The solenoid structure 1000 adopts a modular design, which is easy to disassemble and maintain, suitable for long-term online operation, and reduces the cost and difficulty of cleaning the pipeline.

[0042] (4) Automated and intelligent control: It can be combined with modern control technology to achieve automated regulation. The magnetic field strength and frequency are adjusted in real time through the monitoring system to ensure that the best sterilization effect is maintained under different working conditions, reduce manual intervention, and improve the intelligence level of the system.

[0043] (5) Safe and reliable: It can avoid the corrosion or pipeline damage problems that may be caused by traditional chemical cleaning.

[0044] In some embodiments, adjacent solenoid modules 10 are connected by a movable connector 20, which is suitable for placement at bends or non-bends in the water pipeline. The movable connector 20 allows multiple short solenoid modules 10 to rotate freely and adapt to various complex pipe shapes. This not only ensures the flexibility and versatility of the solenoid structure 1000 for the magnetic heat cleaner of water pipelines in this embodiment, enabling it to smoothly adapt to complex pipe shapes such as bends and branches without affecting the normal flow of water, but also avoids the blockage problems that may be caused by traditional long solenoid structures 1000, which are not relatively movable, at pipe bends, thus ensuring the normal operation of the cleaner in various pipe environments.

[0045] In some embodiments, the movable connector 20 is a telescopic universal joint. The telescopic universal joint allows multiple short solenoid modules 10 to rotate freely and adapt to various complex pipe shapes. This not only ensures the flexibility and versatility of the solenoid structure 1000 used for the magnetic heat cleaner of water pipelines in this embodiment, but also enables it to smoothly adapt to complex pipe shapes such as bends and branches without affecting the normal flow of water. It avoids the blockage problem that may be caused by the traditional long solenoid structure 1000, which cannot move relatively on its own, at pipe bends, thus ensuring the normal operation of the cleaner in various pipe environments.

[0046] Preferably, the telescopic universal joint is made of high-strength materials. Using high-strength materials such as stainless steel ensures that the telescopic universal joint has good mechanical strength and corrosion resistance, enabling it to withstand long-term water pressure and chemical corrosion in water pipelines.

[0047] In some embodiments, the solenoid module 10 includes a solenoid body 101, a cylindrical frame 102, and a shock absorber 103. The solenoid body 101 generates a strong alternating magnetic field and is fixed to the outer periphery of the cylindrical frame 102, which supports and fixes the solenoid body 101. The shock absorber 103 is fixed to the outer periphery of the cylindrical frame 102 and supports the inner wall of the water supply pipe, creating a gap between the solenoid body 101 and the inner wall of the water supply pipe to prevent the solenoid body 101 from impacting the water supply pipe when the solenoid module 10 is installed inside the water supply pipe. This solenoid module 10 has a simple structure, is robust and durable, and can operate stably for extended periods in harsh environments.

[0048] In some embodiments, the multiple solenoid modules 10 may be the same or different in size, which allows the solenoid modules 10 to flexibly adapt to the complex shape of the water pipeline.

[0049] In some embodiments, the number of turns, wire diameter, and length of the solenoid body 10 are determined according to the diameter and length of the corresponding water supply pipeline. To ensure the solenoid module 10 performs optimally in different water supply pipeline systems, key parameters such as the number of turns, wire diameter, and length are customized during the manufacturing process. These parameters are tailored to the actual specifications of the water supply pipeline, ensuring that the solenoid module 10 can generate a highly adaptable and uniformly distributed magnetic field, maximizing the effect of magnetothermal cleaning.

[0050] In some embodiments, the solenoid body 101 includes a metal solenoid and an insulating layer covering the surface of the metal solenoid. The metal solenoid has good electrical conductivity, effectively conducting current and generating a high-frequency alternating magnetic field. The insulating layer covering the surface of the metal solenoid prevents leakage and prevents water, the cylindrical frame 102, and the anti-collision component 103 inside the water pipe from becoming conductive, thus ensuring the long-term safety of the solenoid structure 1000 for the magnetic thermal cleaner of water pipelines in this embodiment.

[0051] In some embodiments, the metal solenoid is a high-conductivity metal solenoid, which can be made of copper or aluminum, and can effectively conduct current and generate a high-frequency alternating magnetic field. The insulation layer is made of a high-temperature resistant and corrosion-resistant insulating material, such as polyimide, which has good high-temperature resistance and corrosion resistance, thus improving the long-term safety of the solenoid structure 1000 used in the magnetic thermal cleaner for water pipelines in this embodiment.

[0052] In some embodiments, the telescopic universal joint is connected between the cylindrical skeleton 102 of adjacent solenoid modules 10, making the connection convenient.

[0053] In some embodiments, the radial cross-section of the cylindrical frame 102 is circular or polygonal. This can be determined according to actual needs. Both the cylindrical frame 102 and the anti-collision component 103 are made of high-strength, corrosion-resistant insulating material.

[0054] In some embodiments, the magnetic field frequency and intensity of the multiple solenoid modules 10 are independently controlled. Since the number and distribution of clam larvae vary significantly in different water supply pipes, independently controlling the magnetic field frequency and intensity of the multiple solenoid modules 10 allows for real-time adjustment of the magnetic field intensity and frequency generated by the solenoid modules 10 according to the degree of clam contamination in the corresponding water supply pipe. This ensures that the magnetic nanoparticles can rapidly heat to the temperature required to kill the clam larvae. By monitoring and adjusting the magnetic field generated by the solenoid modules 10, the solenoid structure is always kept in optimal operating condition.

[0055] The following is a specific example to describe the solenoid structure 1000 for a magnetic heat cleaner for water pipelines according to an embodiment of the present invention.

[0056] Suppose that in a hydroelectric project, the diameter of the technical water transmission pipeline is 250mm, the pipeline material is steel, and the total length of the pipeline is approximately 10m. This water transmission system is facing a problem of fouling by clams, which is seriously affecting normal operation, and an efficient solution for removing clams is needed.

[0057] To address this, a magnetic thermal clam cleaner was designed, employing a solenoid structure 1000. This structure ensures the solenoid structure 1000 can adapt to pipes with small bending radii and complex piping systems while effectively killing clam larvae. During implementation, the solenoid, through its modular design, allows for flexible installation and maintenance, and can be customized to meet specific application needs.

[0058] (1) Material selection for solenoid body 101:

[0059] ① Solenoid material: Highly conductive and corrosion-resistant copper tubing is selected to ensure long-term stable operation in aquatic environments while providing excellent current conductivity. The diameter of the copper tubing is chosen to be 5mm, which can withstand strong electromagnetic induction under high-frequency current without overheating or material deformation.

[0060] ② Insulation layer material: To ensure no leakage of current during transmission and to prevent direct contact between the current and the water inside the pipe, a layer of high-temperature resistant and corrosion-resistant polyimide insulation material is wrapped around the copper pipe. This material can withstand the heating effect of high-frequency electromagnetic fields while maintaining its insulation properties.

[0061] (2) Design parameters of solenoid module 10

[0062] Based on the specific conditions of the water pipeline, the following solenoid design parameters are determined:

[0063] ① Length of solenoid module 10: Each solenoid module 10 is 0.1m long. Multiple short solenoid modules 10 are connected in series to ensure that they can adapt to pipes with small bending radii.

[0064] ② Number of turns of the solenoid body 101: Each solenoid body 101 has 5 turns, which can generate a uniform and strong alternating magnetic field.

[0065] ③ Number of modules: 3 solenoid modules 10 are arranged and connected by universal joints to ensure their flexibility.

[0066] (3) Fabrication of solenoid module 10

[0067] ① Preparation of copper tubes with insulation layer: Prepare copper tubes according to the designed wire diameter and length. Each copper tube is 1m long and is used to wind each solenoid module 10.

[0068] ② Winding process: Precise winding is performed using a specialized winding machine. The copper tube is evenly wound onto a mandrel with a diameter of 50mm, maintaining a constant pitch to ensure that each solenoid is wound 5 turns. The coils are arranged tightly and neatly to avoid gaps that could cause uneven electromagnetic fields.

[0069] ③ Support structure installation: After winding, the solenoid is installed on a high-strength, corrosion-resistant polyethylene cylindrical frame 102. The design of the cylindrical frame 102 must ensure that the solenoid is not easily deformed by water flow impact when installed in the pipe, while ensuring its flexibility to adapt to the bending parts of the pipe.

[0070] (4) Design and connection of telescopic universal joints

[0071] To accommodate small-radius bends, a telescopic universal joint was designed, allowing multiple short solenoid modules 10 to rotate freely and adapt to pipes of various complex shapes. The manufacturing process is as follows:

[0072] ① Material selection for telescopic universal joints: High-strength stainless steel is selected to make telescopic universal joints to ensure that they have good mechanical strength and corrosion resistance, and can withstand long-term water pressure and chemical corrosion in water pipelines.

[0073] ② Manufacturing process of telescopic universal joint: Multiple telescopic universal joints are manufactured through precision machining. Each telescopic universal joint is connected to the adjacent solenoid module 10 at both ends to ensure stable connection and flexibility, adapt to small turning radii in the pipeline, and avoid bending stress or blockage of the solenoid module 10 in the pipeline.

[0074] ③ Connection steps: Each solenoid module 10 is connected in series with adjacent solenoid modules 10 via a telescopic universal joint, ultimately forming a whole device whose length can be flexibly adjusted. This design ensures that the solenoid module 10 can smoothly pass through various bends, branches and narrow areas in the water pipeline.

[0075] (5) Magnetic field frequency and intensity control module

[0076] To achieve the optimal magnetocaloric effect, an intelligent control module was designed to adjust the magnetic field frequency and intensity via an external power supply. The fabrication steps of this intelligent control module are as follows:

[0077] ① Control circuit design: Through precise circuit design, a suitable alternating magnetic field frequency range (long wave to medium wave frequency, usually 10-100kHz) for removing clams from the water pipeline is selected. The control circuit can adjust the magnetic field strength and frequency generated by the solenoid in real time according to the degree of clams contamination in the pipeline, ensuring that the magnetic nanoparticles can be rapidly heated to the temperature that kills clam larvae.

[0078] ② Power Controller Installation: The intelligent control module is connected to an external power supply and a solenoid via a signal cable to ensure real-time monitoring and adjustment of the magnetic field status. The power controller is installed in an equipment compartment outside the water pipeline for easy maintenance and operation.

[0079] (6) Installation and debugging

[0080] After the solenoid structure 1000 is completed, it is installed inside the actual water supply pipeline. The installation steps are as follows:

[0081] ① Modular installation: Based on the actual length of the water pipeline, the solenoid modules 10 are connected sequentially using telescopic universal joints and laid out along the inner wall of the pipeline. Due to the excellent flexibility of the solenoid structure 1000, it can smoothly pass through bends, branches, and narrow sections in the water pipeline.

[0082] ② Electromagnetic Field Testing and Debugging: After installation, connect the intelligent control module to the external power supply, start the system, and perform initial debugging. Using an electromagnetic field testing instrument, ensure that the magnetic field strength and frequency generated by the solenoid within the water pipeline meet design requirements, activating the magnetic nanoparticles and rapidly heating them to achieve the effect of killing the swamp clam.

[0083] ③ Mudskipper Removal Test: After system debugging, a preliminary mudskipper removal experiment was conducted to monitor the mortality rate of mudskipper larvae in the pipes and the removal of attached materials. Based on the test results, the magnetic field strength and frequency were further adjusted to ensure the system can operate efficiently and effectively over the long term.
